A comparison of classmate and self-evaluation of dysphoric and nondysphoric Chinese students

Forty dysphoric and thirty-nine nondysphoric Chinese college students participated in this study. Subjects completed forms on performance standard setting, self-evaluation, and self-perceived efficacy for their academic performance and social skills. Two classmates of each subject were asked to appraise the subject's level of academic performance, social skills, and academic efficacy. The results showed that although there was no difference between the standards the subjects set for themselves in the two groups, dysphorics showed lower self-evaluation, and self-perceived efficacy than nondysphorics. In comparison with their classmates' appraisals, dysphorics rated themselves lower both on their academic performance and social skills, whereas their efficacy judgements coincided with their classmates' appraisals. The findings suggest that depressed people are sadder but not wiser when self-evaluation and self-efficacy are taken into consideration.     

The Interaction of Mood and Rumination in Depression: Effects on Mood Maintenance and Mood-Congruent Autobiographical Memory

Rumination is a response to distress in which individuals focus repetitively on their feelings and the causes and consequences of those feelings. When induced to ruminate, dysphorics exhibit more negative mood and recall more negative memories, but these effects are not seen in nondysphorics. This pattern of results could be due to trait-like differences between dysphoric and nondysphoric individuals, or to the high levels of negative affect that dysphorics are experiencing at the time of rumination. The purpose of this study was to evaluate the effects of pre-rumination mood on post-rumination mood and subsequent memory. Participants scoring high or low in depressive symptoms were assigned to either a positive or negative emotion induction prior to ruminating and completing an autobiographical memory task. Analysis of self-reported mood indicates that both emotion inductions were effective. Surprisingly, all participants returned to baseline mood levels following the rumination induction, and emotion induction had no effect on the negativity of the memories recalled. Dysphorics recalled significantly more negative memories than nondysphorics, regardless of whether positive, neutral, or negative memories were specifically prompted. Our results indicated that the prolonged experience of dysphoria may have greater effects on post-rumination mood and memory than the transitory experience of sadness.     

I don’t care about others’ approval: Dysphoric individuals show reduced effort mobilization for obtaining a social reward

Past research on reduced reward responsiveness in depression and dysphoria has mainly focused on monetary rewards. However, social rewards are important motivators and might be especially impaired in depression. The present study tested the hypothesis that nondysphoric individuals would mobilize more effort during a memory task without a clear performance standard when anticipating social approval for good performance. In contrast, dysphoric individuals were expected to be less sensitive to this reward and to mobilize less effort. Effort mobilization in this 2 (dysphoric vs. nondysphoric) × 2 (no reward vs. social approval) between-persons study was operationalized by participants’ cardiovascular reactivity. Results confirmed that nondysphorics had higher reactivity of systolic blood pressure, diastolic blood pressure, and heart rate when expecting to enter their name in the alleged “best list”, whereas dysphorics had lower cardiovascular reactivity. The present study expands evidence for reduced reward responsiveness in depression and dysphoria from an effort mobilization perspective by demonstrating reduced effort-related cardiovascular reactivity to social rewards.     

Stimulus Exposure Duration in a Deployment-of-Attention Task: Effects on Dysphoric,Recently Dysphoric,and Nondysphoric Individuals

Examined attentional deployment of dysphoric, unstable, and stable nondysphoric individuals using the Deployment-of-Attention Task (DOAT) while randomly varying stimulus exposure durations. Previous research indicates a nondepressed “protective” bias in attention whereas depressed individuals evidence no bias. The current study examined the possibility that depressed participants' lack of bias may actually reflect inattention to briefly presented stimuli, possibly due to slowed processing seen in depression (i.e. psychomotor retardation). Participants completed the DOAT, viewing stimuli at four presentation durations randomised across trials. Results indicated that dysphoric participants displayed no attentional bias even at extended presentation durations, whereas nondysphoric participants showed a “protective” bias. Within the nondysphoric group, unstable nondysphoric participants displayed a more pronounced protective bias than did stable nondysphorics.     

Accuracy in perceptions of interpersonal interactions: effects of dysphoria, friendship, and similarity.

Conflicting views of depressives' interpersonal accuracy were addressed in an investigation of the accuracy of mild depressives (dysphorics) across differing social contexts. Women who were either friends or strangers and who were either similar or dissimilar in level of dysphoria conversed about 3 topics: a neutral topic, their own disclosure of a personal problem, and their partner's disclosure. Dysphorics were not more accurate in general than nondysphorics. After self-disclosure, all women more accurately detected sympathy from a similar stranger. After the partner's disclosure, women also better detected the mood of a similar partner. When interacting with nondysphoric strangers, however, dysphorics underestimated their partner's sympathy toward them. Implications for cognitive and interpersonal theories of depression and for depressives' relationships are discussed.     

Cognitive mechanisms underlying implicit negative self concept in dysphoria

Whereas explicit measures of the self-concept typically demonstrate a negative bias in depressed individuals, implicit measures such as the Implicit Association Test (IAT), revealed an opposite, positive bias. To address this inconsistent pattern, the authors examined, using a novel paradigm, mental set maintenance (i.e., the difficulty of maintaining active a required mental set) and set operation (the efficiency of executing the mental set while it is maintained). Dysphoric (N = 33) and nondysphoric (N = 30) participants alternated between an IAT focusing on self reference and a matched neutral task. Nondysphorics had greater difficulty in maintaining a negative self reference task compared to a neutral task. Conversely, dysphorics did not exhibit such difficulty, and they maintained a negative self-reference task more easily than nondysphorics. No group differences were evinced in smoothness of set operation. These results suggest that the shield protecting nondysphorics from maintaining negative mental sets is absent in dysphorics.     

Fingertip aura and interpersonal attraction

Concluding from our survey of the literature that fingertip auras (Kirlian effect) might be associated with interpersonal attraction, four hypotheses were advanced to test this assertion. It was hypothesized that individuals would respond with bigger auras to (1) opposite-sex photographers as compared to same-sex photographers, (2) to seductive opposite-sex photographers as opposed to normally behaving opposite-sex photographers, (3) to opposite-sex unknown peers as opposed to same-sex unknown peers, and (4) to liked as opposed to disliked same-sex persons. All hypotheses except (2) were supported. The second hypothesis was significant in a direction contrary to hypothesis. Fingertip auras are seen as a promising measurement device in the study of interpersonal attraction.     

Depression impairs the ability to ignore the emotional aspects of facial expressions: Evidence from the Garner task

We assessed dysphoric and clinically distressed individuals' ability to ignore the emotional aspects of facial expressions using the Garner speeded‐classification task. Garner's paradigm tests the ability to selectively focus on a single relevant dimension while ignoring variations on other, irrelevant, ones. In the present task, the stimuli were faces of men and women expressing happy, angry, and neutral emotions. In Experiments 1 and 2, dysphoric and nondysphoric participants performed the Garner task, focusing on gender and ignoring emotion (Experiment 1) and focusing on emotion and ignoring gender (Experiment 2). Results suggest that dysphoric individuals exhibited more difficulty ignoring the emotional dimension of social stimuli even under specific instructions to do so than nondysphoric individuals. In Experiments 3 and 4, we replicated these results in clinically distressed and nondistressed individuals. The results of Experiment 3 further suggested that depression was more closely associated with the inability to selectively ignore emotion than was social anxiety. Experiment 4 confirmed that this failure of selective attention was specific to processing emotional, and not gender features. The implications of these findings for cognitive and interpersonal theories of depression are discussed.     

Dual-task attention deficits in dysphoric mood

The attentional functioning of nondysphoric, mildly dysphoric, and moderately to severely dysphoric college students was tested using the attentional blink (AB) paradigm. These groups performed equally well at reporting a single target appearing in a rapidly presented stream of stimuli. All groups showed an AB, with report sensitivity for a 2nd target being reduced when the 2 targets were presented less than 0.5 s apart. Nondysphoric and mildly dysphoric participants showed the same size ABs, but the ABs for moderately to severely dysphoric participants were larger and longer. As predicted, the results showed that moderately to severely dysphoric individuals have attentional impairments. These impairments, however, were evident only in the more demanding dual-task condition.

Reversed mnemic neglect of self-threatening memories in dysphoria

Previous research has suggested that people have difficulties remembering information which is threatening to the self—an effect known as mnemic neglect. Three experiments are presented that examined mnemic neglect in dysphoria and whether dysphoric individuals show enhanced memory for self-threatening information. Pilot work determined that dysphoric participants rated central negative traits as more important than nondysphoric participants. In Experiment 1, dysphoric participants were found to have better memory for self-threatening information than nondysphoric participants. Enhanced recall of self-threatening memories was also found for unmodifiable (Experiment 2), and highly diagnostic (Experiment 3) self-threatening traits. The findings suggest that dysphoric participants show reversed mnemic neglect effects indicating enhanced access to negative information relating to the self.

Adult Detection of Children's Selfish and Polite Lies: Experience Matters

Five groups of participants (N = 150) with differing amounts of experience working with children were assessed on their ability to detect children's lying or truth telling. Children's lies were told for antisocial reasons (i.e., self‐serving lies) and for prosocial reasons (i.e., to benefit others). Overall, adults were more accurate at identifying children's dishonest statements than their true statements, and children's antisocial lies were detected more accurately than were their prosocial lies. While adults without experience were poor at detecting child lie tellers and truth tellers, adults with extensive child experience were better at distinguishing children's lies and truths.     

Peer interactions of dysphoric adolescents

The present study sought to extend our knowledge of dysphoric adolescents' dyadic peer interactions. Thirty female dyads (ages 13–17) were videotaped interacting during both a structured and an unstructured task. Fourteen of the dyads were each comprised of a dysphoric girl and a nondysphoric girl; the remaining dyads were comprised of two nondysphoric girls. Girls were considered dysphoric if they scored 10 or higher on the Beck Depression Inventory. Dysphoric subjects evaluated their performances more negatively than nondysphoric subjects and rated their partners more negatively overall. The partners of the dysphoric girls were viewed by raters as less positive and less happy. They saw the dysphoric teens as making more critical comments and evaluated them more negatively overall. There was also a tendency for these girls to reject their dysphoric partners and to become more passive during the unstructured task. The findings indicate that dysphoric adolescent girls evoke negative reactions from peers and negatively influence their peers' behavior. These negative reactions from others may lead to further difficulties in negotiating the developmental tasks of adolescence.     

Moderately dysphoric mothers behave more positively with their infants after completing the BDI

To determine whether mildly and moderately dysphoric adolescent mothers display infantized facial and vocal behaviors, 21 nondysphoric mothers and 32 dysphoric (16 mildly and 16 moderately/severely dysphoric) mothers were videotaped during face-to-face interactions with their 4-month-old infants. Mildly dysphoric mothers showed less positive facial expressions and less animated/exaggerated vocal expressions. The moderately/severely dysphoric mothers, however, did not differ from nondysphoric mothers in their display of facial and vocal behaviors. These mothers with higher Beck Depression Inventory (BDI) scores may have become concerned about their many symptoms affecting their interactions and tried to compensate for this during their interactions. A second study was conducted to determine whether completing the BDI before interactions positively affected the moderately/severely dysphoric mothers' behavior. Moderately/severely dysphoric mothers (N=24) and mildly dysphoric mothers (N=24) were given the Beck Depression Inventory either before or after their face-to-face interactions with their 4-month-old infants. Moderately/severely dysphoric mothers who were given the BDI before their interactions showed more positive behavior than mothers given the BDI after their interactions. © 1997 Michigan Association for Infant Mental Health     

Motivated social categorization: fundamental motives enhance people's sensitivity to basic social categories

This article presents an evolutionary framework for identifying the characteristics people use to categorize members of their social world. Findings suggest that fundamental social motives lead people to implicitly categorize social targets based on whether those targets display goal-relevant phenotypic traits. A mate-search prime caused participants to categorize opposite-sex targets (but not same-sex targets) based on their level of physical attractiveness (Experiment 1). A mate-guarding prime interacted with relationship investment, causing participants to categorize same-sex targets (but not opposite-sex targets) based on their physical attractiveness (Experiment 2). A self-protection prime interacted with chronic beliefs about danger, increasing participants' tendency to categorize targets based on their racial group membership (Black or White; Experiment 3). This work demonstrates that people categorize others based on whether they display goal-relevant characteristics reflecting high levels of perceived desirability or threat. Social categorization is guided by fundamental evolved motives designed to enhance adaptive social outcomes.     

Conflict behaviors toward same-sex and opposite-sex peers among male and female late adolescents

Differences between males and females in regard to conflict behaviors toward same-sex and opposite-sex peers were examined in a sample of 501 undergraduate university students (326 males, 175 females). They completed a one-page questionnaire containing the theoretical definitions of five conflict behaviors identified by Thomas (1976): competing, avoiding, accommodating, compromising, and collaborating. Students were asked to rate the extent to which they exhibit each of these conflict behaviors, on a 5-point Likert-type scale, separately for same-sex and opposite-sex peers. Results revealed that males reported more competing behavior toward same-sex peers than toward opposite-sex peers, and more avoiding behavior toward opposite-sex peers than toward same-sex peers. Males, compared to females, reported more accommodating behavior toward both same-sex and opposite-sex peers. These findings support the view that preferences regarding conflict behaviors are different for males and females, particularly as exhibited toward same-sex and opposite-sex peers.     

Depressive realism and attributional style: implications for individuals at risk for depression

Prior research has found that depressed individuals are more realistic in their interpretations of certain events than nondepressed individuals. However, the implications of this finding for the etiology of depressive disorders have never been clarified. The current investigation sought to remedy this situation by exploring realism in the context of a well-validated, cognitive diathesis-stress theory of the etiology of a subtype of depression: hopelessness theory (Abramson, L. Y., Metalsky, G. I., & Alloy, L. B. (1989). Hopelessness depression: A theory-based subtype of depression. Psychological Review, 96, 358-372). A sample of 239 college students, including groups of participants with depressogenic versus nondepressogenic attributional styles, recorded the causes they assigned to events; the extent to which their attributions were objectively realistic was evaluated. A comparison of the degree of objectivity was also made between dysphoric and nondysphoric individuals. Contrary to expectations derived from the depressive realism hypothesis, dysphoric individuals exhibited less realistic attributions as compared to nondysphoric individuals. Further, individuals at risk for depression evidenced a pessimistic bias, while individuals not at risk evidenced an optimistic bias.     

Sex Composition of Groups and Member Motivation II: Effects of Relative Task Ability

This study examined the effects of group members' relative task ability on the relationship between group sex composition and member task motivation. Male and female subjects performed a simple motor task with an opposite-sex partner, a same-sex partner, or no partner. Partners had higher, equal, or lower task ability than subjects. When the partner was more able than the subject, both sexes did more work with an opposite-sex partner than when working individually, whereas subjects with a same-sex partner did no more work than individual controls. Group sex composition did not affect member motivation when the partner was equally or less able. These findings disconfirmed several models of the sex composition-motivation relationship. They supported an esteem maintenance model which holds that both sexes place greater value on demonstrating competence to opposite-sex partners than to same-sex partners.
